Subject: Patch for video bugs + Max's additions

I've attached a patch for today's CVS that includes Max's virtual
mouse button fix as well as some other changes:

-building mode list correctly now (had duplicate entries, was unsorted)
-switching modes correctly now (wasn't destroying previous mode)
-releasing memory correctly in event loop

    31     TODO
    32         - Hardware Cursor support with NSCursor instead of Carbon
    33         - Keyboard repeat/mouse speed adjust (if needed)
    34         - Multiple monitor support (currently only main display)
    35         - Accelerated blitting support
    36         - Set the window icon (dock icon when API is available)
    37         - Avoid erasing window on minimize, or disable minimize
    38     Problems:
    39         - OGL not working in full screen with software renderer
    40         - SetColors sets palette correctly but clears framebuffer
    41         - Crash in CG after several mode switches
    42         - Retained windows don't draw their title bar quite right (OS Bug)
    43         - Should I do depth switching for windowed modes? - No, not usually.
    44         - Launch times are slow, maybe prebinding will help
    45         - Direct framebuffer access has some artifacts, maybe a driver issue
    46         - Cursor in 8 bit modes is screwy
    47         - Modifier + mouse-down maps alternate mouse button, but if modifier is released
    48            before mouse button, corresponding mouse-up event is not generated.
    49         - Clicking in content activates app, but doesn't generate the activate event,
    50           and subsequent switches generate no activate/deactivate events! (OS Bug I hope)
